The International English Language Testing System exam (IELTS) is a British exam similar to the American TOEFL which tests the students’ English language proficiency and is used for applying to western institutions. The IELTS is accepted by most UK, Australian, Canadian and New Zealand academic institutions.
The IELTS exam has two versions that can be chosen from by the student, the Academic or General and there are two kinds of reading and writing tests - called modules. Both modules are held at the same time and in the same room as the listening and speaking parts. You can choose the module you want to take at registration.
The Academic Module is usually taken when applying for higher education or study abroad, or by doctors doing the PLAB test and the General Training Module is usually taken when applying for immigration to Canada, Australia or New Zealand.
The Writing, Reading and Listening sections of the test are usually taken together. The Writing and Reading parts last for an hour each and the Listening part takes about 30 minutes. The Speaking test is taken separately or on the same day, and lasts from 15-20 minutes.
